Summary

This study tracked viral load in saliva, throat, and nose samples collected daily from newly infected individuals. The findings show each sample type follows a distinct viral-load trajectory, with saliva and throat detecting infection earlier than nose. This has major implications for COVID test accuracy, sampling strategies, and future pandemic preparedness.
